A Methodology For Analyzing Mobility Levels In Small Cities: Lessons Learned In Grand Junction, Colorado

This paper shows the results of an analysis to measure the mobility level in Grand Junction, Colorado. Researchers at the Texas Transportation Institute have monitored urban mobility levels in many of the nation’s largest urban areas while refining a methodology that can be used in smaller areas and even applied at the individual roadway level. This specific analysis had two objectives. The first objective was to obtain a mobility level for the city. The second was to test the methodology and determine any refinement needed since previous uses for the methodology were in national scale studies. The local agencies in Grand Junction, in conjunction with the Colorado Department of Transportation (CDOT), chose seven arterial street corridors for the analysis. In October 2000, travel time data and traffic counts were collected along these corridors for use in the study. The results of the analysis show that the average peak hour trip on these seven corridors in Grand Junction takes about 7 percent longer to complete because of higher traffic demand. Since this study was one of the first to apply this methodology in the field, a great deal of information was learned in the process. This information is documented in this report so it will be available the next time a mobility analysis such as this is performed. Some of the lessons learned include: (1) The data collection plan is critical to the study process. (2) Pre-collection and post-collection meetings should be scheduled. (3) Local feedback on raw data and findings are needed. (4) This analysis is most useful at a corridor level and not on a segment-by-segment basis. (5) The data collected in this analysis may be useful for other analyses as well.
